This Planning Letter adds Allstream (CLEC) to the list of the Test Number providers for NPA 825.

In Telecom Decision CRTC 2013-574 dated 30 October 2013, the Canadian Radio- television and Telecommunications Commission (CRTC) directed that relief for Alberta area codes 403/587/780 be provided through a distributed overlay of a new area code 825 starting 9 April 2016.

New area code 825 has been assigned by the North American Numbering Plan Administrator and will be implemented on the Relief Date of 9 April 2016 as a distributed overlay over the geographic area of the province of Alberta currently served by the 403, 587 and 780 area codes. A map showing the location of the area served by NPAs 403, 587 and 780 is attached to this letter.

When the new 825 NPA is introduced, no changes will take place to the dialling plans in the area that is served by NPAs 403/587/780 and will be served by NPA 825. The dialling plan in this area will continue to be:

- all local calls including Extended Area Service calls will be dialled with 10 digits; and, - toll and alternatively billed calls will be dialled with 10 digits after the appropriate prefix digit(s).

All international and domestic Telecommunications Service Providers (TSPs) should activate the new 825 NPA throughout their networks by the start date for network testing (10 January 2016).

The following test numbers for the new NPA 825 will be made available effective 10 January 2016. Routing of calls to NPA 825 can be verified by dialling the 8378 (TEST) numbers which do not provide answer supervision. Billing of calls to NPA 825 can be verified by dialling the 2455 (BILL) numbers which provide answer supervision.
